IMPRovEMEN'r IN vAPoR-BURNERS.

Specification forming part of Letters Patent No. 188,283', dated March 13,1877; application tiled November 18, 1876.

To all whom it may concern:

Beit known that I, GEORGE W. GLoUGH, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Burner; andl do herebydeolarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and 'use it, reference beingl had to the accompanying drawings, which form part of this specification. e

My invention relates to an improvement in vapor-burners; and consists, first, in providing such burners with an expansion-cham ber, situated between the outlet and the Vaporizin g-cham'ber, whereby a more steady and even iow ofthe vaporized hydrocarbon uid is secured,

It also consists in an adjustable plate, which forms the lower part of the burner, whereby the character of the flame can be determined.

It further consists in such parts and combinations as will hereinafter be more fully set tional view of a vapor-burner embodying my invention. Fig. 2 is an enlarged view of that part of the burner embracing the expansionchamber. Fig. 3 is a detached view of the adjusting-plate. Fig. 4 is a similar view of the perforated combustion-cap.

A is a pipe, which leads from and is connected with an elevated reservoir, (not shown in the drawing,) whence the gasoline or hydrocarbon duid comes for burning, in the ordin-ary well-known manner. Connected with said pipe A is the vertical tube B, the upper part of which forms the vaporizing-chamber D. Around said partof the tube B is situated the primary heating-cupv C. Above the vaporizing-chamber is placed the expansionchamber N, from which leads the passage or outlet a. The sides of said chamber are beveled or funneled at their lower end, as shown at d, and the angle of said bevel is made to correspond with that of the tapering part of the screw-pin valve E, so as to secure a very tight and close fit, in order to eifectually prevent leakage. The lower part of the rod of the valve E is screw-threaded, which works .in the female screw in the projection R. Said rod is provided with a hand-wheel, P, or other suitable device, by which the supply of the vaporized uid is regulated. As it is turned in either one or the other direction, the tapering or pin-pointed valve E is lowered or elevated, and thereby an annular space at d is formed, or enlarged', contracted, or entirely closed, thus permitting or cutting off the dow of the duid. H is the top plate, provided with a central opening. It is 'supported on the arms Gr Gr, which rise from the sides of tube B, at the top thereof, and serve to establish a free open space between the mouth of the outleta and the burner, for the purpose of securing combustion. I is the adjusting-plate, provided with a downwardly-projecting guidepipe, b, screw-threaded on the outside, whereby, in connection with the screw-threaded opening of the top plate'H, said adjustingplate I can be elevated or lowered relatively to said topl plate. The guidepipe b is situated directly over the outlet a, from whence the vaporized fluid passes, through said guidepipe, into the perforated combustion-cap K. Said .adjusting-plate is also provided with a circle of openings or jet-apertures, c.

The object in making lthe plate I adjustable,

is to secure in all cases a blue or heating flame. This I have found by experience cannot be obtained in all cases unless the burner is capable of adjustment; but with this improvement the desired result can be reached in all instances, as any difficulties resulting from slight variation in the mechanical construction of different burners, which would, without my improvement, prevent the attainment of a blue or heating ame, can with it, by simple adjustment of the plate I up or down, be at once overcome. K is the perforated combustioncap, provided with one or more series or circles of jet-apertures, c. It fits to the periphery or sides of plate I loosely, so that it can be taken off or removed when desired. One advantage thereby secured is, that in case the opening or outlet a becomes clogged or I l stopped up, the instrument by which to clear it can be passed through the tube b from above, in a line with the axis of outlet a, thus diminishingA the liability of injury to the outlet, aswell as facilitating its cleaning. A

By means of the expansion-chamber N a very steady and even liow of the vaporized uid through thc outlet a is secured, and any of the fluid which escapes vaporization in the chamber D, and enters the expansionchamber N, is vaporized therein, so that by this improvement a thorough vaporization of the gasoline or hydrocarbon tluid is secured.

The operation of the device is as follows' The gasoline or hydrocarbon fluid enters the tube B by hydrostatic pressure. To light the burner, turn the Wheel P so as to open the valve E. This will cause a jet of duid to pass through the opening a into the combustioncap K` striking against the roof or top thereof.` The uid will run down into the cup C, and when the same is about half full, close thevalve E to stop the How. Then light the uid in the cap and let it burn out. This operation heats the upper part of tube B sufciently to cause vaporization of the fluid to take place in the chamber D thereof. Now, when the valve is opened again the vaporized fluid passes into the combustion-cap, and issues at the jet-apertures c c c', Where, when lighted, it burns with a blue ame, Which can be regulated as desired by openingthe valve more or less. The vaporized fluid that passes from the interior of the combustion-cap K through the jet-apertures c issues between the top plate H and adjusting-plate I, and burns with a blue flame, which forms a continuous Sheet around the burner. The heat from the top plate H and from the burner is transmitted, by the arms G and by radiation, to the upper part of tube B to a sufficient extent to continue the vaporzation of thegasoline in the chamber D, which was secured, in

the rst instance, by the direct application of heat by means of the cup C.

Any number of these burners may be connected with and supplied by the same'reser- Voir, limited, of course,only by the capacity of the latter. v

The interior of the guide-pipe b is preferably made tapering, with the smaller end opening into the combustion-cap K.

'What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with the combustioncap K, of the adjustingplate I, the latter constructed with guide-pipe b, substantially as and for the purpose set forth.

2. The combination, with perforated adjusting-plate I, of the combustion-cap K, removably secured to the outer edge of said adjusting-plate, substantially as and for the purpose forth.

3. In a vapor-burner, the adjusting-plate I, provided with guide-pipe b and jet-apertures c', substantially as described.

4. The combination, with plate H, of the perforated adjusting-plate I, provided `With guide-pipe b, substantially as and for the purpose set forth.

5. ln combination with the vaporizing-chamber D, expansion-chamber N, and screw-valve E, the adjusting-plate I and removable cap K, substantially as and for the purpose described.

6. The combination, with the vaporizingchamber D, "expansion-chamber N, and screwvalve E, of the adjusting-plate I, top plate H, and removable combustion-cap K, substantially as described. f

7. The combination, with the vaporizingchamber D, expansion -chamber N, screwvalve E, and primary heating-cup C, of the adjusting-plate I, top plate H, and removable combustion-cap K, substantially as described.

8. The combination, with the vaporizing-` chamber D, expansion-chamber N, screwvalve E, and primary heating-cup G, of the arms G G, adjusting-plate I, `top plate H, and removable combustion-cap K, substantially as described. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
